Hello all, 
I am kind of exhausted right now and I want to make sure I have this down correctly?  Can I have a foci that provides a benefit to earth magic like this, or is it violating the way benefits have to be broken up, and it needs to have a +1 in 3 different effects like +1 to earth offense control, earth defense control, earth defense power?

      -Power:                  +1
